Hi Vinay,

The below IP details at your Head and Branch office...

MPLS IP @ Head office : 10.1.22.21 - 10.1.22.22
INTERNET IP @ Head Office : 1.2.2.2 /30
Head office LAN : 192.168.0.0/24
MPLS IP @ Branch Office : 10.1.22.24 - 10.1.22.25
Brach Office LAN : 192.168.1.0 /24

What is the MPLS router IP and the Management Vlan IP at your head office?

I hope you have a default route configured in your MPLS router at head office like below...

0.0.0.0 0.0.0.0 1.2.2.1

I guess your management VLAN IP at your head office is 192.168.0.1, is that right? If YES

Then you can add a default route like below at your branch office MPLS router to go to the internet traffic on to head office internet link....

0.0.0.0 0.0.0.0 192.168.0.1

Dear Naidu,

@ My head office i terminated both (Internet & MPLS ) Links on same router.

head office Mpls Router IP is : 10.1.22.22

Branch Office MPLS Router IP is : 10.1.22.25

ASA (Default Gateway For Head office LAN) : 192.168.0.1

Is this possible that my BRANCH Office LAN Users can use Internet & follow ASA Rules @ my Head Office after this command :

0.0.0.0 0.0.0.0 192.168.0.1

Hi Vinay,

Yes, it should work please check and update...

And make sure the default gateway at head office LAN: 192.168.0.1 is reachinv over MPLS.

Regards,

Naidu.

Dear Naidu,

Thanks for Help..

I will let you know after this is done..

i just need to put a static route na:

Like :\

@ Head office to reach Brach Office LAN :

ip route 192.168.1.0 255.255.255.0 10.1.89.21

Default Route for internet : 0.0.0.0 0.0.0.0 1.1.1.1

@ Brach Office:

ip route 192.168.0.0 255.255.255.0 10.1.89.24

For Internet Access : 0.0.0.0 0.0.0.0 192.168.0.1

Is this right ?

[Latchum Naidu]

Hi Vinay,

Yes, that should work out.

I hope you have already the static routes defined at your head office.

And only thing you have to do at branch office.

Is that correct?

Regards,

Naidu.
